Summary
Cancer stemness drives metastasis and relapse. Glucose-regulated protein 78 (GRP78) is key to cancer stemness, offering a target to eradicate cancer stem cells and prevent tumor recurrence.
Area of Science:
- Oncology
- Cell Biology
Background:
- Cancer stem cells (CSCs) are implicated in tumor metastasis and relapse post-therapy.
- Key CSC properties include self-renewal, low population percentage, and distinct substance absorption.
- The precise mechanisms maintaining cancer stemness are not fully understood.
Purpose of the Study:
- To review the discovery and characteristics of cancer stem cells.
- To explore the role of glucose-regulated protein 78 (GRP78) in maintaining cancer stemness.
- To discuss targeting GRP78 as a therapeutic strategy against CSCs.
Main Methods:
- Literature review of cancer stem cell research.
- Analysis of studies investigating GRP78 function in cancer.
- Synthesis of evidence linking GRP78 to cancer stemness properties.
Main Results:
- Cancer stemness contributes significantly to tumor progression and therapeutic resistance.
- GRP78 has been identified as a critical mediator of cancer stemness.
- Targeting GRP78 presents a promising approach for CSC eradication.
Conclusions:
- Understanding cancer stemness is crucial for developing effective cancer treatments.
- GRP78 is a viable molecular target for eliminating CSCs.
- Targeting GRP78 may offer a novel strategy to overcome metastasis and relapse.

Cancer Stem Cells and Tumor Maintenance
5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

Targeted Cancer Therapies
7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Mitogens and the Cell Cycle
6.6K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Treatment Resistant Cancers
3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Replicative Cell Senescence
3.7K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
